Packaging material performance requirements -- mechanical properties

In the process of the flexible packaging production printing and composite film need to withstand the tension, after dressed up with food to bear the gravity of the content, to withstand the impact during the process of transportation, handling may even occur in the process of falling and should withstand the impact, so the packaging material tensile yield stress and elastic modulus, tensile fracture stress index is very important for the flexible packaging.
If poor mechanical properties of the film, it will happen in the process of printing misregister, gravity after guangdong food packaging creep, after the shock, and even rupture occurred.
